Intrusive Thoughts and Fear: How Anxiety Quietly Took Over My Life

A personal essay on fear, intrusive thoughts, and living with health anxiety

I woke up at 2.30am this morning to a loud clang. My first thought was great, here we go again, the tiles are doing their party piece. When I say tiles, you probably would not believe this, but our floor tiles have been popping for the past three years. By popping, I mean a sharp, sudden bang that happens periodically, especially towards the end of the summer. We have underfloor heating and as the temperature drops, the adhesive beneath the tiles contracts and they pop loose. You genuinely could not make it up.

But this time it was not the tiles. One of Sam’s toys had somehow launched itself off the top of his wardrobe and landed on the tiled floor in his bedroom. To both Joanne’s and my shock, it did not wake him, which felt like a small mercy at that hour.

Once I am awake, however, I rarely fall straight back asleep. My mind starts moving, and last night it drifted exactly where I knew it would. I knew I would be writing this post later today, and I began thinking about how I wanted to approach it. This feels like my first step outside my comfort zone, writing about something that has been sitting with me for a long time, something I have never really named properly before.

The word fear, for me, brings with it worry. There is a strain of worry that has lived with me since childhood and followed me into adult life. Over the years though, that worry has changed shape. In more recent years, it has become something heavier. It has become fear.

I can pinpoint the exact moment it arrived. I was on a work trip to London in 2014, just three weeks before my wedding. I had been helping to run an event for our London based clients. It hit me on the flight home, in the middle of a thunderstorm. A sudden, intrusive thought. What if this is it. What if the plane goes down. I will never get married. Complete and utter catastrophising.

From that moment on, the way my mind worked changed. The wiring shifted. The thoughts became louder, more convincing, harder to shake. This is not a post about how I fixed it, or how I rewired my thinking, or how I meditated my way out of it. That is not my story.

This is for people who think like I do. For people who read endless posts about mental health fixes, breathing techniques, and tidy solutions, and still feel unseen by them. The harsh reality is that what often gets left out are the symptoms themselves, the lived experience of what it actually feels like to carry this kind of fear day to day.

I have carried this for nearly ten years in its current form. My greatest fear, especially since Sam has come along, is the idea of not being here. What happens if I only have a short amount of time as a dad. To finally reach this point in my life, to achieve the thing I wanted most, only to lose it too soon. That thought winds my brain up beyond belief. It spirals quickly into questions of purpose and meaning, and the catastrophising ramps up until everything feels fragile.

I think that fear is one of the reasons I have been so determined to get healthier over the past couple of years, particularly from an eating and lifestyle perspective. I want time. I want to be here for a long time. I want to be present for Sam, especially as an older dad. But that same fear can also tip into something unhelpful, where I start thinking too far outside my own life, absorbing everything that is going wrong in the world. Doomscrolling. Bad news. Catastrophe layered on catastrophe. There is misery everywhere if you go looking for it, and I do not need to carry all of it.

My world is much smaller than that. It is Joanne. It is Sam. It is Alfie padding around the house. That is my triangle, or the square if you include the dog. Everything else is noise.

Recently, Joanne and I were watching YouTube and decided to show Sam some older videos we had appeared in on his Auntie Karen’s page, LovelyGirlyBits. Watching them back caught me off guard. What struck me was not just that I had far fewer grey hairs, but that I seemed different altogether. Lighter somehow. Less burdened. Possibly quite immature, which Joanne was quick to point out, but different all the same.

There was an ease to me in those videos that I do not always recognise now. A looseness. A version of myself that was not constantly scanning for what might go wrong next. Watching it made me realise that while life has changed and responsibilities have rightly grown, I do not want to lose that version of myself entirely. I think part of what I need now is to meet him somewhere in the middle. Not to go backwards, but to carry some of that lightness forward with me.

Fear has narrowed me over time. It has quietly shrunk my world without me noticing. Where I once moved through life with ease, I now often move through it anticipating consequence. Some of that is adulthood. Some of it is responsibility. But some of it is fear taking up more space than it deserves.

I do not think fear arrived without reason. A lot has happened in the past decade. Marriage. Loss. IVF. Grief. Becoming a father. The stakes feel higher now because they are higher. Fear is tied directly to love, and I understand that. But understanding it does not stop it from exhausting you.

What I am slowly learning is that fear does not respond well to being fought head on. Trying to logic it away or suppress it rarely works. It just finds another way in. What does help, at least a little, is shrinking its world back down to size. Reminding myself what actually matters, and what does not deserve my attention.

Fear still shows up, often late at night, often uninvited. It still asks the same questions. What if you are not here. What if this ends early. Those thoughts are not going anywhere. But I am trying to meet them differently now. Not by indulging them, and not by pretending they do not exist, but by grounding myself back in the life that is actually happening in front of me.

That is why health has mattered so much to me recently. Not aesthetics. Not numbers. Time. I want time. I want to show up as a dad without being hijacked by constant fear. That motivation has been stronger than anything else.

I am not writing this because I have answers. I do not. Fear is still very much part of my life. But I am starting to see that living alongside it might be more realistic than trying to eliminate it altogether. I am trying to reclaim some of that lightness I saw in those old videos, not by denying reality, but by choosing where I place my attention.

This is the first post in a series where I want to explore these things honestly. Fear. Purpose. Depression. Overcoming. Not as concepts to fix, but as experiences to understand. If any of this feels familiar, you are not alone in it. And if nothing else, writing it has helped me name something I carried quietly for a long time.

That feels like a start.
